A sidelink communication method performed by a UE is provided. The method includes receiving from a base station a message including zone configuration information and resource pool configuration information and selecting a zone type mapped to a speed of the UE among zone types indicated by the zone configuration information. A zone identifier is determined based on configuration information of the selected zone type, the configuration information of the selected zone type being included in the zone configuration information. The sidelink communication is performed using a resource pool mapped to the zone identifier among resource pools indicated by the resource pool configuration information.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The sidelink communication method according to claim 1, wherein the plurality of zone types are classified into a high-zone and a low-zone, the high-zone and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a speed threshold, and the low-zone is selected among the plurality of zone types when the speed of the UE is less than the speed threshold.
3. The sidelink communication method according to claim 2, wherein the zone configuration information includes the speed threshold.
4. The sidelink communication method according to claim 2, wherein the resource pool configuration information includes configuration information of resource pools for the high-zone and configuration information of resource pools for the low-zone.
5. The sidelink communication method according to claim 1, wherein the plurality of zone types are classified into a high-zone, a medium-zone, and a low-zone, the high-zone, the medium-zone, and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a first speed threshold, the medium- zone is selected among the plurality of zone types when the speed of the UE is less than the first speed threshold and equal to or greater than a second speed threshold, the low-zone is selected among the plurality of zone types when the speed of the UE is less than the second speed threshold, and the first speed threshold is greater than the second speed threshold.
6. The sidelink communication method according to claim 1, wherein the message is a system information block (SIB).
9. The operation method according to claim 8, wherein the plurality of zone types are classified into a high-zone and a low-zone, the high-zone and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a speed threshold, and the low-zone is selected among the plurality of zone types when the speed of the UE is less than the speed threshold.
10. The operation method according to claim 9, wherein the zone configuration information includes the speed threshold.
11. The operation method according to claim 9, wherein the resource pool configuration information includes configuration information of resource pools for the high-zone and configuration information of resource pools for the low-zone.
12. The operation method according to claim 8, wherein the plurality of zone types are classified into a high-zone, a medium-zone, and a low-zone, the high-zone, the medium-zone, and the low-zone have different sizes, the high-zone is selected among the plurality of zone types when the speed of the UE is equal to or greater than a first speed threshold, the medium-zone is selected among the plurality of zone types when the speed of the UE is less than the first speed threshold and equal to or higher than a second speed threshold, the low-zone is selected among the plurality of zone types when the speed of the UE is less than the second speed threshold, and the first speed threshold is greater than the second speed threshold.
